Description

Hylocereus costaricensis is an intriguing succulent cactus for a variety of reasons. Even though it is ground-dwelling, the slender leafless stems flop and clamber as if a vine, gaining support from tree trunks, rocks or walls. It is renowned for its large white nocturnal flowers, up to 12 inches (30 cm) long and wide, that are very short-lived. Following blossoming, it produces edible, scaled fruits with vibrant magenta-fuchsia flesh littered with tiny black seeds. The leathery, fleshy stems have three ribs, each topped with tiny clusters of short spines. There are no leaves, but instead photosynthesis occurs in the green stems. In summertime, large flower buds arise on the stems. Each opens at night and remains open a few hours, releasing perfume to attract bat pollinators. The pale yellow-green bud leaves fold back and look like petals surrounding the true white petals. The oval fruit – called Pitaya or Strawberry Pear – that follows weeks later is vibrant red and edible.

How to Grow and Care

Like most cacti, Cereus are fairly low-maintenance and hardy. Make sure they receive enough water without becoming waterlogged, especially during the summer, and fertilize them for best results. If the roots have become black or overly soft, the cactus could be experiencing root rot – cut away the affected parts and replant. Most gardeners interested in cacti should be able to cultivate these without much problem.

It may become necessary to repot your Cereus if it outgrows its container. If so, make sure the soil is dry and then remove the pot. Knock away old soil and prune away any rotted or dead roots, then replace it in a new pot and backfill with new soil. Make sure not to overwater cacti planted in new pots, as this can lead to root rot – it should be left dry for about a week and then watered lightly… – See more at: How to Grow and Care for Cereus.
